The radar-guided weapon was developed in the 1970s and can down targets as high as 72k feet, well above the altitude of Flight MH17.

TheUkrainian government has blamed pro-Russian separatists, who deny responsibility.

Russian President Vladimir Putin vowed that his country will do everything it can to end the conflict in eastern Ukraine, which has now claimed lives of nearly 300 people who were aboard Malaysia Airlines Flight 17.
